CPP also sells rear disc brake kits; it is bolt on except for a tab for the emergency brake (if you want to run an e-brake) that welds onto the rear axle. The grand slam kit had everything I needed to rebuild my front and rear suspension, front brakes, and drop how much I wanted.
Their rear disc kits are $599, look on page 2 of the truck section. If you need to rebuild your suspension the grand slam is great, I absolutely love mine. If not, they sell drop kits with spindles, rotors, calipers, that utilize all your original tie rods, ball joints etc.
